thanks for your question costochondritis is inflammation of the junctions where the upper ribs join the cartilage that holds them to the breastbone (sternum). Costochondritis causes localized chest wall pain and tenderness that can be reproduced by pushing on the involved cartilage in the front of the rib cage. Costochondritis is a relatively harmless musculoskeletal chest pain and usually resolves without treatment. visit a pulmonologist and reevaluate the cause and continue with the medications in my patients i usually first check for other causes like cardiac diseases and lung diaeases and gastritis by requesting some investigations like chest xray , ecg , 2 d echo and ct scan if needed and of it is costochondritis i prescribe them analgesics or NSAIDS as needed you beed to consult a pulmonologist who can guide you thanks feel free to ask more questions may god bless younwith good health
